MAX3491EESD Description

Short technical summary and product information.

The MAX3491EESD from Analog Devices (Maxim Integrated) is a +3.3V low-power transceiver designed for RS-485 and RS-422 communications. This device features enhanced electrostatic discharge (ESD) protection on its I/O pins, rated up to ±15kV using the Human Body Model and IEC 1000-4-2 standards.

 

This transceiver supports full-duplex communication and can achieve data rates of up to 12Mbps. It operates from a single +3.3V supply and is interoperable with +5V logic. The device includes current-limiting and thermal shutdown circuitry for driver overload protection, and the receiver input has a fail-safe feature.

 

The MAX3491EESD is available in a 14-SOIC package and is designed for surface mount applications. Its operating temperature range is -40°C to +85°C, making it suitable for various industrial and telecommunication applications.

 

Key features include ±15kV ESD protection, a single +3.3V supply, guaranteed 12Mbps data rate, and a -7V to +12V common-mode input voltage range. It also offers a low-current shutdown mode.
